AUTOMOBILE-RADIATOR.

Specification of Letters Patent. Patented Oct. 12, 1915,

Application viled March 28, 1914. Serial No. 827,929.

To all whom t vmay concern.' f

Be it known that I, FREDERICK NY. SPEN- CER, a citizen of the United States, residing` at Ionia, in the county of` Ionia and State of Michigan, have invented certain 'new and useful Improvements in Automobile-Radiators, of which the following is a specification. y f

This invention relates to automobile radiators, and has as its object to `provide a radiator which will be light in weight, although lexceptionally strong and durable, and which will have aemaximum radiating area as compared with the space occupied by the radiator as a whole. y

The radiator embodying the present invention is of that type comprising a number of assembled sections, and it is an aim. of the invention to so construct the sections that they may be readily assembled and disassembled, and may be added to or\removed as desired.

In the accompanying drawings: Figure 1 isa front elevation of the radiator embodying the present invention. Fig. 2 is a vertical sectional view therethrough on the line 2-2 of Fig. 1. Fig. 3 is a sectional perspective view of one upper corner of the radiator. Fig. #i is a similar sectional view on the line of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying d 'rawings by the same reference characters.

As before stated, the radiator is made up of a' number' otl sections, and these sections are of counterpart form, except for certain minor details to be presently explained.y In the drawings but two .of the sections are shown, but, as will be presently made clear, any desired number may be employed,de

pending of course upon the character of engine employed.

In the drawings, one of .the sections is indicated ingeneral b v the letter A and the other by the letter B, the section A being the forward-section and the section B being the rear or inner section. Each section comprises essentially a hollow frame-like body,

.the front wall of which is indicated by the numeral 1. the rear wall by the numeral 2,

vand the surrounding, or top. bottom and side walls, by the numeral 3. The forward section A is provided in its top with a filling spout 1, having a cap closure 5,'and the section B has led into it through its rearv Wall,

l.a pipe 6, which leads from the water jacket of the engine, and a pipe 7, which leads from the radiatorto the said water jacket, the pipe 6 being located near the top of the radiator and the pipe 7 being disposed near the bottom of the radiator, as is customary. Each section is, of course, provided with an inner wall 8 which is spaced from the .Wall 3, and fitted at their upper and lower ends in the top and bottom walls of the inner wall 8 respectively, are tubes 9,' the tubes of each section being preferably arranged in staggered relation, as clearly shown in Fig. l of the drawings, and' each tube having arranged upon it a. number of radiating disks 10, which may be circular or of any other desired outline; or, if desired, a spiral or.

similar radiating flange may .be provided upon each tube. It ,is v preferable that a screen 11 be secured upon' the front of the forward section A, so as to protect the tubes of the radiator from dust and dirt.

TheA front wall ofthe forward' section A is formed adjacent its corner with anopening 12, and the rear wall of the said section is formed adjacent each corner with an vopening 13, tubes 14 beingsecured within the hollow, bodyv of the section and registering at their' ends with the said openings 12 and 13. These tubes are provided each with a number of openings 15, the purpose of which will be presently made clear. Ina

' like manner, the forward wall of the section B is formed near each corner with an opening llvand -its rear wall is similarly formed with openings 17, thel tubes'lS corresponding to the tubes 11, being arranged within the hollow body of thexsaid'section B and registering at their'ends with the'said openings 16 and 17 f. lVhen the sections are assembled, theyy are disposed in the manner shown infFigs. 2, 3 and 4, and bushings 19 are fitted in the adjacent ends of the corresponding tubes 14: Jand 18,' and serve to establish communication between the said tubes. If desired, however, the bushings 19 may be secured in the tubes 1S and may project beyond the forward face lof the rear section B, so as to nt within the rear ends of the tubes 14, when the sections are assembled. Prior to thus assembling the sections, packing gaskets or washers 20 are fitted one upon each of the bushings, so that when the sections are clamped together, the Washers 2O will be compressed and a )vater tight `ioint will be effected between the sections at the point of location of the said tubes. As a means for clamping the sections together, tie-bolts 21 are fitted through the washers 22 and 23 disposed respectively against the forward face of the section A, and rear face of' the section B, the said washers closing respectively the openiiigs 12 and 17, and a nut 21 is threaded on to each tie-bolt yand bears against the respective washer 23the l hea-d of the bolt bearing against the corresponding washer 22, and the shank of the bolt extending through the tubes 11 and 1S and the said bushing 17.

From the foregoing, itlwill be apparent that -water entering the section B through the pipes 6 which `fill the hollow body of' the Section and its radiator tube 9, will fiow through 'the openin-gs in the tubes 18 and through these tubes and the bushing 19 into the tube 1l, from which it will pass through the openings 15 into the hollow body and tubes ofthe section A, the return flow being through the lower ones of' thetubes 11 and 1S and out through the pipe 7. The washers Q2 and 23 are Vpreferably pro.

vided .with reduced portions Q2 andl 23 which fitjwithln the openings 12 and 17 respectively, and serve to prevent leakage by completely .closing theseopenings. "hen it is juxtaposed similar hollow frame-like sec- Copies of this patent may be obtained for tween the sections and entering the oppos ing ends ot' the flanged tubes, gaskets mounted upon the bushings, washers closing the openings in the outer walls ot the sections, and tie-bolts passing through the washers and the flanged tubes and connecting the several sections. y I

2,'A` water cooling radiator for internal combustion engines, the same comprising a plurality of' frame-like sections having openings in their front and rear walls 'in coincident' relation, tubes extending across the space formed'between the inclosing hollow members of each of the sections and connecting the inner Walls thereof, other tubes disposed between the front and rear walls of each of the sections in line with the openings formed in such walls and having their extremities outwardlyiianged and such tubes having openings in their sides, bushings extending across the joints formed between -the sections and havingv their ends inserted in the opposing ends of adjacent flanged tubes, gaskets 'mounted upon the bushings between the sections, washers closing the openings in the outer walls of the sections, and tie-bolts passing through the washers, flanged tubes and bushings and connecting the several parts. In testimony whereof 1 `affix my signature 'in presence of two witnesses.
